在使用webpack打包时，将css代码从bundle.js中抽离出来，单独出一个模块，需要用到extract-text-webpack-plugin插件
webpack版本不同，相对于的插件也不同，如下：
# for webpack 4 npm install --save-dev mini-css-extract-plugin # for webpack 3 npm install --save-dev extract-text-webpack-plugin # for webpack 2 npm install --save-dev extract-text-webpack-plugin@2.1.2 # for webpack 1 npm install --save-dev extract-text-webpack-plugin@1.0.1
之前版本使用方法，可参照：https://github.com/webpack-contrib/extract-text-webpack-plugin
在webpack4中，用mini-css-extract-plugin替代。
webpack.config.js:
const MiniCssExtractPlugin = require(‘mini-css-extract-plugin‘); module.exports = { plugins: [new MiniCssExtractPlugin( filename:‘./css/[name].css‘ )], module: { rules: [ { test: /\.css$/i, use: [ { loader: MiniCssExtractPlugin.loader, options: { publicPath: ‘../‘
hmr: process }, }, ‘css-loader‘, ], }, ], }, };
